A massive blizzard dubbed "Snowzilla" dumped 68cm of snow in New York's Central Park, and paralysed Washington DC over the weekend.
Near-record-breaking snowfall was piling up in cities up and down the East Coast, and as the storm ended, thousands came out to enjoy the fresh snow.
Here's a look at some of the antics people got up to:
Casey Neistat, who runs a popular YouTube channel, went snowboarding on the streets of New York on Saturday. He did not have rope so he resorted to using a 30-foot (9m) HDMI cable, he told Buzzfeed. He cruised through Times Square raising an American flag, and performed stunts with a friend who skied. His video had more than 18 million views on Facebook by Monday (Jan 25).
Mr Neistat and his friend were not the only ones who broke out a snowboard and skis.
Others went snow diving and swimming in the powdery snow.
Dancers boogied in the snow.
In West Virginia, the thick layer of snow became a makeshift freezer.
And it wasn't just humans having fun. Videos captured a Giant Panda at the Washington National Zoo frolicking in the snow.
Dogs revelled in the cold weather.
So did this Tyrannosaurus Rex.
Princess Elsa from Disney cartoon Frozen came out for a spin too.
